Board Installation
1-F. Fan Connectors (FAN1, FAN2)
Fan1
is for the CPU fan.
The
Fan2
connector is for the Chassis Fan.
1-G. CD Audio Connector (CD1)
1-H. Video-In (VIDEO1)
Video-in ATAPI Header for external multimedia
devices.
1-I. COM2 port header (COM2)
This is the connector header for the COM2 Port.
1-J. Front Side USB Header (J2)
Certain computer chassis allow for two front-end
USB port connections. This board provides a front
side USB header should you decide to set up a USB
connector at the front side of your computer.
1-K. EXTSMI Server Management Connector (JP1)
The EXTSMI (External System Management Interface) connector JP1 is used by some
plug-in cards. Certain applications associated with these plug-in cards use the interface
for hardware control and queries.
1-L. Power Management (JP18)
STR is part of the ACPI system, which provides energy saving functions for the
computer. If this jumper is set to NOT ENABLED (close pins 2-3) which is the
default setting, the system will default to S1 state, even if the BIOS has ACPI
functions enabled. If the jumper is ENABLED (close pins 1-2), and ACPI functions
are enabled in the BIOS, the system will go to energy saving S3 state (hibernation),
saving the systems state into volatile memory.
1-M. Sleep Button (JP24)
The sleep button jumper is connected to the front panel sleep button (if one exists).
The purpose of this jumper is to provide for manual activation of the BIOS power-
saving state.
